Do you know how engineers measure noise?
Measuring jet noise isn’t as simple as turning up the volume.
Engineers use a scale called dB(A) that adjusts for how the human ear hears sound.
At NASA Glenn Research Center, scientists use microphones and lasers to study how heat and turbulence create sound.
Pretty cool, right?
Did you know about this before watching the video?
